HIGH TEMPERATURE TELECOM BATTERIES

2

C&D Technologies has been on the leading edge of standby battery development since 1906. Always pushing the limits, C&D strives to provide our customers with the most advanced battery technology on the market.

As standby battery applications become increasingly demanding, the batteries that support these applications must be improved to provide reliable service and long life in diverse environments.

With this in mind, C&D has introduced the TEL High Temperature Series VRLA batteries, featuring MSE Pure Lead Plus Technology. The TEL High Temperature Series takes the best features from the industry-leading msEndurll 2V VRLA, C&D’s TEL Long Duration Series' proven reliability, and the unmatched design of C&D’s TRUE Front Access series to provide, the most reliable 12V VRLA battery available. In accelerated life testing, the TEL High Temperature series provides 12+ years of life under normal operation, and is able to deliver reliable performance even in high temperature environments.

Much of C&D’s success in the telecom market can be attributed to its quality and advanced technologies, providing customers with a reserve power solution they can depend on. With power requirements increasing and space decreasing, a shift towards VRLA products became necessary. C&D embraced this challenge with the TEL Long Duration Series with a proprietary high density active material and robust grid design that provided a documented 10+ years of life in industry-standard footprints. The Long Duration Series was enhanced in 2008 with the introduction of True Front Access designs that gave customers increased energy density and simplified maintenance without sacrificing reliability. For sites with larger power requirements and increased reliability concerns, the pure lead msEndurII is used. The MSE technology used in the msEndurII reduces the float current required to keep these batteries at a full state of charge, resulting in slowed corrosion rates and a 20 year service life. The advanced technologies developed in each of these products have been combined into one long life, high energy density product family, the TEL High Temperature Series.

The benefit of using high purity materials, including high purity oxides, is a reduction of gassing reactions on float The benefit of using high purity materials, including high purity oxides, is a reduction of gassing reactions on float charge. Optimized Grid Lead alloys also limit corrosion, particularly intergranular corrosion of the positive grid. charge. Optimized Grid Lead alloys also limit corrosion, particularly intergranular corrosion of the positive grid.

WHAT IS MSE PURE LEAD PLUS TECHNOLOGY?The TEL High Temperature Series features MSE Pure Lead Plus Technology, providing long life and exceptional performance in uncontrolled temperatures. C&D uses a proprietary Ball Mill Oxide made with ultra-high purity positive and negative active materials in addition to specialized processing techniques. This high-tech recipe creates a well-balanced cell that operates with reduced float current similar to a flooded cell, slowing grid corrosion and limiting water loss typically associated with traditional VRLA batteries.

ADVANTAGES ◆ Reduced Grid Corrosion ◆ Reduced Float Current ◆ Slower Aging Mechanisms ◆ 2X Longer Life in Float Operation

◆ Longer Storage Life ◆ Reduced lnternal Temperature and Water Loss ◆ Stable Operation at High Temperatures

C&D developed the MSE Pure Lead Plus Technology to fundamental change the way our batteries operate that leverage this innovation. The effects on the active material are measurable and lower float currents are achieved using a high density, large pore structure in the active materials through proprietary plate manufacturing processes and low corroding positive grid alloys. Low float currents allow batteries to operate at higher temperatures while minimizing risks of thermal runaway. The result is a longer battery life as seen in the graph below.

STRONG DESIGNIn any application where the battery may face extreme temperature, shock, or vibration conditions, a rugged case is key to maintaining battery performance over time. All TEL-HT batteries are encased in strong polypropylene that protects all the battery’s components and ensures that the battery will work year after year in the most demanding environments.

One of the leading causes of VRLA battery failure is water loss. As a VRLA battery ages, it will start to lose water more rapidly, leading to dryout and decreased capacity. The MSE Pure Lead Plus Technology in the TEL High Temperature reduces water loss by up to 50%, a critical component to long life at high temperatures.
